AUTOMOBILE BUMPER.

.OriginaI application filedi October 5,1925, Serial No. 00,405,. Divided and this application filed May 16, 1928 Serial No. 278,171 7 This invention relates to automobile bumpers and has for an object the provision of a spring-bar-bumper comprising an impact section including a plurality of fiat metal bars superimposed in'the same vertical plane and spaced Vertically, extending all the way across the front of the bumper and having their ends recurved to form lndividual end loops, the recurved ends 'of; the component 10 members being edge bent diagonally toward each other and meeting, near the loops, at a point where the ends are joined toeach other and are also joined to the ends of a rear bar which extends'for a considerable portion of its lengthin substantial parallelism with the impact bars,,serving to connect the joints The above described bumper forms the subject of generic claims in mycopending application Serial No. 60,405, filed October 6,1925, from whichthe present application has been divided.

A further object of the present invention is toprovide a modified bumper of the abovetype in which means are provided to connect the'rear bar and impact members 'at one or more points between the ends thereof, such means taking the form of a plurality of spac- 40 mg or cushion members which are preferably interposed between the rear bar and the impact bars toward the ends of the impact section. These cushion members are preferabl secured both to the rear and to the impact-h as for example, by clamps extending between and connecting the impact bars to each other and to one end of the cushion members,'the other ends of the cush on members be1n'g'de-- sirably'bolted or riveted to the ends of the recurved loop members and also to the ends of the rear bar, at the joints therebetween.

ars,

Such additional connections between the rear bar and the impact bars afford additional rigidity at regions where impacts of unusual violence may be expected in use.

' Other features of the invention will appear from the subjoined specification and claims and are illustrated in thedrawings.

In the drawings, I 1 I H Fig. 1 is a view in front elevation of an automobile bumper in the construction of which the invention has been embodiedQf' Fig. 2 is a plan view thereof.

In theillustrated embodiment, referring to Figs. land 2, the reference numerals 1 and 2 designate upper and lower impact'bars, preferably formed of flat resilient strips of steel arranged in the same vertical plane and spaced vertically, substantially asillust'rated, these bars extending throughout the entire length of the bumper, and constitutin an impact section at the ends of which the ars I 1 and 2 are rec'u'rved to form, separate loops 3 preferably lying each in the horizontal plane ofits particular impact member,'and beyond these loops the end portions 4 and 5 of members 1 and 2 are shown as edge-bent diagonally toward each other, joining at a region near the ends of the loops, where they are secured together as indicated at 6, by suitable'devices such as rivets or bolts.

In pursuance of the invention a rear bar is shown at 7 extending in substantial parallelisin with the impact section and spaced therelroi'i'i throughout the greater, or a lesser, portion of its length,as may be desired, the form of rear bar illustrated in Figs. 1 and 2 being parallel with, and spaced. from, the

impact section, for substantially the entire length of the rear bar, and each end ofthe rear bar is bent forward, as at 8 into substantial parallelism with the-diagonally bent end members 4 and 5, to which the end portions "8 of the rear bar are-preferably secured, as

for example by the samebolts and rivets 6 which connect the impact bars to each other,

so that a single joint suliices to complete the bumper-structure at these regions.

The impact members are desirably con.- nected to each other also by clamps 9 and 18 whichalso serve as means to maintain the vertically spaced relation of the impact members.

Y The bumper may be attached to a vehicle by c any suitable devices, not shown, these devices being'custoin'arily attached to the rear bar 7 at points between the center and ends thereof on each side of the center. 7 v v In further pursuance of the invention, I provide a spacing member or flexiblecushion 15 near each loop 3, and preferably interposed between the impact section and rear bar at the region oi thejoin't 6 on each side, the member lfi having one of its ends secured to the recurved loop ends l and 5 by the same riyets or bolts 6 which connect the ended and with the ends 8 of the rear bar, the ends 8 being embraced between the end portion 16 of rhemember 15 and the loopend portions 4a'nd5. f f V The forward ends 17 or the members '15 extend toward, and are preferably secured to, the impact section, as by means of the clamps 18 which connect the top and bottom impact bars to each other and which are connected in turn to the portion 17 of the members 15 by bolts 19 and nuts 20. I

This form of bumper provides for a somewhat greater rigidity, of a y1elding' character however, in the vicinity of each or" the end loops 8. than in bumpers not having said cushion members and this type of structure is particularly serviceable Where heavy im-i pacts are to b'oj guarded against, proceeding toward the-ends of the bumper.

Havingdescribed my invention, I claim 1.,A bumper comprising a rear bar, and

an impact section including a plurality of vertically spaced parallel frontbars extending throughout the length of the bumper and recurved to form end loops connected to each other and to the rear bar by diagonal members and spacing members between said rear barand impacts'ection near the ends of the latter. V

2. A bumper comprising a rear bar, and an impact section including a plurality of vertically spaced parallel front bars extendrecurved to form end loops connected to each other and to the rear bar 'by'd iagonal memhers, and curved cushronsp'acing members secured to said iimpact section near the end loops andsecured also tothe aforesaid rear connecting joints by devices passing through said cushion members and loop ends with the corresponding ends-0t said rear bar embr ce'd therebet'ween. v 1
